Abstract
In an ion generating unit configured to control driving of a plurality of ion generating elements for generating ions by a controller, the controller drives the ion generating elements upon start up, and is configured to keep driving for a predetermined time period; thereby, the ion concentration of a space upon start up is quickly raised to a predetermined concentration. Further, the controller is configured to drive the ion generating elements intermittently and one after another in order after the predetermined time period has elapsed; the product life is elongated while maintaining the predetermined ion concentration and shortening the driving time of the ion generating elements.
